Slurry seal is a mixture of well-graded fine aggregate with mineral filler and dilute asphalt emulsion. A single course is usually applied in thicknesses of 3–6 mm (1/8–1/4 in.). Slurry seals are effective in areas of excessive oxidation and hardening of the existing asphalt and are used for sealing minor surface cracks and voids, retarding ...
Description. Mix designs are an integral part of the overall performance of Slurry Seal, Microsurfacing and Chip Seals. For mix design of Slurry Seals and Micros, there are several recommended sources including ASTM D3910, ISSA A-105 & ISSA A-143, and MS-19 Basic Asphalt Emulsion Manual.In the lab, blending of the materials that are to be used in the field is …
The field verification phase involved evaluating the ability of the laboratory procedure to design slurry seal mixtures that could be constructed satisfactorily and would perform adequately under various traffic and environmental conditions. This was accomplished by examining mix and performance data for 6 projects between 1984 and 1986.

The thickness of this Sealing is about 3 to 10 mm dependent on the place condition and after about 2 hours, traffic can pass on it. It is better to apply Slurry Seal when the road surface temperature is at least 10 °C and there isn't any risk of freezing within the first 24 hours after implementation. Slurry Seal's life time is 3 to 5 years.

Slurry Seal Checklist 6 Slurry Seal Paver The slurry seal paver is fully functional and can accurately proportion and deliver materials through a pugmill. All paddles in the pugmill are intact and not severely worn that could limit the mixing ability. Each paver has been calibrated using the materials specified in the project mix design.
About this product. Abrasion-resistant and corrosion-resistant metal components and silicon carbide seal faces extend seal life beyond slurry pump components to maximize equipment uptime. Robust construction handles slurry particle hardness up to MOH 9 and slurry concentration up to 60% solids by weight for reliability in the toughest services.
Slurry seal is a cold mix coating consisting of fine crushed aggregate, emulsified asphalt, additives, and water applied to roadways. Emulsion serves as a binder to hold the aggregate together and to adhere to the roadway. Slurry seal is very economical and extends the life of pavement up to 7 years.
Slurry Seal Vs. Microsurfacing Differences in: MICROSURFACING SLURRY SEAL Mix Stiffness/ Equipment stiffer mix, use augers in the spreader box and secondary strike-off softer mix, use drag box Applications same as slurry seal + rut filling, night work, correction of minor surface profile irregularities correct raveling, seal oxidized pavements,
What is Slurry? Slurry seal is a mixture of aggregate, asphalt emulsion, and filler, which are mixed together according to a laboratory's design-mix formula. water is also added for workability. Asphalt emulsions serve as a binder, holding the crushed aggregate together and adhering the new slurry surfacing to the old surface over which it is ...
Slurry Seal – inaczej cienkie warstwy bitumiczne na zimno – to technologia polegająca na wypełnianiu nierówności, kolein oraz wykonaniu cienkiej nakładki (do około 2 cm.) na powierzchni remontowanej drogi przy pomocy półpłynnej mieszanki mineralno- emulsyjnej wytworzonej w specjalistycznym kombajnie.
• Slurry seal is a thick solution that is primarily for use on streets and roads where traffic is heavy or moving at high speed. • A slurry seal produces a revitalized protective surface that prolongs the life of the pavement beneath it. • Because of the size of the aggregates in a slurry seal, the surface will be rougher and have better ...
A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the emulsion and aggregates represents "slurry.".
